• Console Log Stream information using ffmpeg node.js

  5 mars 2019, par Matteo

  I have created a work application that links in room encoders to live stream onto Facebook, Twitter and Youtube. I am wondering as to how to properly log the stream quality on the CMD. Below are snippets of the code and where I think the logic should be to properly pull the stream quality and display it in the cmd :

  Pushing Stream :

      if (req.query.french_facebook) {
  
    var streamComplete = req.query.fb_fre_streamURL + req.query.fb_fre_streamKey;
  
    temp = checkValidity('Facebook', 'French', req.query.fb_fre_streamURL, req.query.fb_fre_streamKey, status);
  
    status = temp[0];
  
    valid = temp[1];
  
    if (valid == true) {
  
      var command = `ffmpeg -re -i ${inputURL2('French',req.query.fb_fre_venue)} -c:v copy -acodec aac -ac 1 -ar 44100 -x264-params keyint=60:scenecut=0 -strict -2 -f flv "${streamComplete}"`;
  
      var process = nodeCmd.run(command);
  
      createStream(req.query.username, 'Facebook', 'French', req.query.fb_fre_streamKey, process.pid);
  
    } else {
  
      console.error("ERROR: unable to create stream");
  
    }
  
  }

  App initialization :

      var createError = require('http-errors');
  
  var express = require('express');
  
  var path = require('path');
  
  var cookieParser = require('cookie-parser');
  
  var logger = require('morgan');
  
  
  
  var indexRouter = require('./routes/index');
  
  var usersRouter = require('./routes/users');
  
  
  
  var app = express();
  
  
  
  var fs = require('fs');
  
  
  
  // view engine setup
  
  app.set('views', path.join(__dirname, 'views'));
  
  app.set('view engine', 'ejs');
  
  
  
  // app.use(logger('dev'));
  
  app.use(express.json());
  
  app.use(express.urlencoded({ extended: false }));
  
  app.use(cookieParser());
  
  app.use(express.static(path.join(__dirname, 'public')));
  
  
  
  app.use('/', indexRouter);
  
  app.use('/users', usersRouter);
  
  
  
  // catch 404 and forward to error handler
  
  app.use(function(req, res, next) {
  
    next(createError(404));
  
  });
  
  
  
  // error handler
  
  app.use(function(err, req, res, next) {
  
    // set locals, only providing error in development
  
    res.locals.message = err.message;
  
    res.locals.error = req.app.get('env') === 'development' ? err : {};
  
  
  
    // render the error page
  
    res.status(err.status || 500);
  
    res.render('error');
  
  });
  
  
  
  module.exports = app;

  If there is anything I am not making clear please let me know

• after 10M ffmpeg stops saving video on nodejs

  12 mai 2016, par cauchy

  I have a nodejs server running using express (express 4). I want to save the video from a few IP cameras on a lab on request. Everything works, but if the video is too long it doesn’t get saved (the limit seems to be 11M).

  I tried using only the command line :

  ffmpeg -i rtsp://192.168.1.189:554/ch01_sub.264 -strict -2 -vcodec
  
  copy -vcodec copy test.mp4

  and this works. But I get into trouble as soon as I use node (note that this is in the node parser, no code in express. I get the same error when running the server) :

  var child_process = require('child_process');
  
  tmpProcess = child_process.spawn('ffmpeg',['-i','rtsp://192.168.1.189:554/ch01_sub.264','-strict','-2','-vcodec','copy','-vcodec','copy',"test.mp4"],{maxBuffer: 10000});

  this runs until test.mp4 is around 11M. tmpProcess is not killed, it keeps running. But after test.mp4 is of certain size I cannot play it back. I get an error saying that "This file contains no playable streams." (this is from Totem, but VLC doesn’t work either).

  Changing maxBuffer doesn’t help. I’m trying to understand what buffer am I overflooding but I cannot get much info from the manual on the api of node.
